Rhomphaia

The rhomphaia was a close-combat bladed weapon used by the Thracians as early as 350-400 BC. Rhomphaias were weapons with a straight or slightly curved single-edged blade. Although the rhomphaia was similar to the falx, most archaeological evidence suggests that rhomphaias were forged with straight or slightly curved blades, presumably to enable their use as both a thrusting and slashing weapon.
